To all 'whom t mag/concern.'

Be it known that l, JOSEPH A. Raison- MANN, Jr;,a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Signal Devices, of which the following is a specification.

My invention relates to improvements in 'signal devices for automobiles and otherV vehicles, andv it pertains more especially to vthat class of signal deviceswhich are operated by electricity, whereby an arm or other signal is brought into view by touching a button or closing an electric c1rcu1t or by any other means, also-whereby a suf nal bell is momentarily and automatically sounded and an electric light is simulta# neously produced. invention also includes a mirror, whereby, aI vehicle or other object approaching from the rear may be seen without the necessity of the operator turning in his seat.

invention is further lexplained by reference to the accompanying drawing, in whichf- Figure 1 represents a front view ot'the device, part in vertical section, the same being drawn on line 1, 1 of Fig. 2.

Fig. 2 isa section showing a signal arm extended, drawn on line 2, 2 ot' Fig. 1.

Fig. 3 is a vertical section showing a por tion of the signal arm in its .lowered position, and

Fig. 4 is a diagrammatic View showing the electric battery, electric wires, switches and signal bell.

Like parts are referred Vto by the same reference characters throughout the several views.

l is an electric battery or other source of electrical energy. 2 is a signal arm upon,

' which the wordFStop or other appropriate signalmay be printed. When used in con nection with an automobile the signal is pretcrably connected with one ot the side men1- bers 3 of the wind shield by bracket/sb, 5 and bolts G; 6, or lin any convenient manner. 7 is a mirror which is pivotally connected with the signal inclosing chamber by lugs 9, 9 and bolt 10. The rear side of the signal arm 2 ispreferably lighted, when raised to the posltlonshown in Figs. 1 and 2, by an electric lamp 11, and said lamp is connected with the battery 1 by the Wires 12, 12 and switch 13. lltis an electric lamp of ordispecication of Letters Patent.

1 or other posite arm 19 is thrown vbrief interval with the arm 29,

'bell 30 is closed and said nary construction, and the same is adapted to be manually connected with the battery source of electrical energy by the wires 15, l5 as the switch 16 is closed. 417 is an electromagnet. "When the switch arm 13 is moved to the arm 18 is drawn down in Contact with one end ofthe electromagnet 17, whereby the opupwardly, whereby the catch 20, formed on the extreme upper end of'the arm 10 is disengaged ,from the recess 21, when such to tthatin'dicated lin dotted lines in said figure, when owing to the slight excess of weight of the arm 2 over that of the armature 23 said arm 2 is caused to move downwardlyfrom the position' shown inl Figs. 1 and 2 to that shown in Fig. 3. The armature 23 is p rovided with a notch or recess, 21, as stated, for the reception of the catch 20, whereby said signal arm 2, when raised, is securely retained in its raised position. The electromagnet 25 is energized the instant the switch 13 is brought in contact with thelower terminal 27', whereby the members 2G are magnetized and cause the armature 23 to be drawn in close proximity to them. When said switch 13 is raised and moved in the opposite direction, and thereby brought in contact withthe terminal 28 the position of said signal arm will be reversed and lowered to the position shown in Fig. 3, as stated. As the arn'iature 23 is given a partial revo lution in either direction on its pivotal support the lug 22 is caused to contact for a `whereby the raten-tenerle. 5, 1919. 'Applicationled October 2, 1916. Serial No. 123,252.

the dotted position shown in Fig. 1`

extreme upper end is caused thereby to contact with thelug 22,

electric circuit between the battery 1 and the bellis thereby automatically sounded for a brief interval during such contact.' The rear part 31 of the inclosure 32 is seiiurel at one side to said inclosure by the hinge 33, while the opposite side of .said inclosurc is provided with an ordinary catch by which such parts are connected together. Having thus described my invention what ll claim as new and desire to secure by Letters Patent, is z- 1. In a device of the described class, the

combination of a signal arm, a stationary` clectromagnet, a pair of circular members secured to the respective ends of said electromagnet, an armature revolubly supported upon said stationary electromagnet, and adapted to revolve'a partial revolution only around said electromagnet, a switch, pair of terminals connected with said switchq said armature being adaptedv to move said signal arm in an upward direction, and means for holding said signal arm when raised, said signal arm being moved downwardly by gravity after having been released from its holdingmeans. 4

2. In a device of the described class, the

.combination of a signal arm, an electromagnet, a revoluble armature pivotally supportedupon said electromagnet, and adapted to revolve a partial revolution around its exterior, an electric battery, electric wires communicating between said battery and said electromagnet, a switch, a pair of terminals connected with said switch, said signal arm being adapted to be moved by said revoluble armature in an upward direction as said armature,performs a partial revolution around said electromagnet, a spring adapted to throw a latch into Contact with one end of A said armature` whereby said latch is caused lto engage a notch in said revohlblc armature, and thereby retain such signal arm in its raised position, and means connected with the other terminals for releasing said latch and signal arm, whereby said signal arm is adapted to drop in the opposite direction by gravity, a signal bell, and mains connected with said battery for autonmtically closing an electric circuit between said battery and signal bell as said signal is moved in either direction.

In testimony whereof I alii-x my signature the presence of two witnesses.
